Thanks I watched the video think that is the one i'm going to getI think I mentioned this before but will add it again:
That loader has 2 rails. The smaller one is for 223 sized cases. The larger one sits a bit further in front and is intended for 7.62x39 size cases. 6.5 Grendel fits there, but they don't load. At least not with my ASC mags, so I don't recommend it for Grendel shooters.
